Origin Search Operation
138
This mode is similar to mode 1, except that the positioning completed input sig-
nal (INP) is also used. The positioning completed input signal from the servo
motor drive is connected to the positioning completed input (A12/B12) of the
PCU’s external I/O connector.

This mode makes use of the origin adjustment function of OMRON Servobmotor
Drives such as the R88D-H/M. It also uses the Servo motor Drive’s positioning
completed input signal (INP) as the origin search completed signal. Do not use a
Z-phase, or error counter reset signal.
Origin Detection Method: 0
Deceleration starts on the rising edge of the origin proximity input signal and the
origin adjustment command is output on the falling edge. Positioning stops on
the rising edge of the positioning completed input signal from the Servo motor
Drive.

Note
When the origin search is completed in Mode 2 or Mode 3, the Servo motor
Drive’s positioning completed input signal is used. The positioning completed
input signal waits for the positioning monitor time (axis parameter). If the monitor
time is set to “0,” the signal waits until the positioning completed input signal
turns ON. Therefore, if a problem exists in the positioning completed input signal
wiring or if the servo gain is set to a large value, the busy state continues without
completing the positioning.
